Coefficient of Inefficiency is a semi-humorous attempt of C. Northcote Parkinson to define the size of a committee or other decision making body at which it becomes completely inefficient.
Parkinson's Law states that "work expands so as to fill the time available for its completion." A more succinct phrasing also commonly used is "work expands to fill the time available."
The Rete Algorithm [References] is intended to improve the speed of forward-chained rule systems by limiting the effort required to recompute the conflict set after a rule is fired. Its drawback is that it has high memory space requirements. It takes adva
